Definitions

  • the invention relates to a steam cleaning device with a water storage tank heated for evaporation, one emerging from the vapor space of the water reservoir Steam line leading to a steam delivery device leads and arranged in a closing or metering valve and with one entering the steam line Liquid water supply.
  • the steam jet to a small extent add liquid water to improve the cleaning effect to improve.
  • Another advantage of the construction described is that the user is disconnected from independent of the water supply during operation is.
  • the liquid water also becomes the water reservoir taken as the water vapor, so that also at the portable one and not connected to a water source Steam cleaning device both operating modes without further can be carried out.
  • the construction described also ensures that when generating a detergent jet in any case, a steam jet is generated, which if necessary, liquid water is added. It is not like other cleaning devices of this type, possible with improper opening of the closing or Dosing valves to produce a pure jet of liquid. Its cleaning effect would be insufficient, on the other hand would produce a pure jet of liquid the water supply is exhausted very quickly, i.e. the levy would be ineffective and undesirable overall. This can be the case with the steam cleaning device described above Kind do not occur because when opening the closing or Dosing valve in the steam line in any case Steam escapes. This closing or metering valve remains closed in the steam line, neither can Liquid jet will leak if in this condition erroneously the dosing or closing valve in the Liquid supply would be opened.
  • the removal of the liquid water from the water reservoir also has the advantage that a liquid withdrawal can only occur when the steam generation has already started to a sufficient extent, because the promotion of liquid water through the Riser pipe takes place under the pressure of the steam in the Steam room, and this pressure builds up when it heats up of the water reservoir only gradually. If he however, it is ensured in any case that sufficient steam delivery is possible, i.e. a Liquid is only dispensed if the Steam delivery is ensured. This is also an incorrect operation locked out.
  • the Steam line has a T-shaped line piece the confluent part of which emerges from the steam room Steam pipe and on its continuous part on the one hand the supply of liquid water and on the other hand the steam line leading to the steam delivery element are connected.
  • the metering or closing valve in the Liquid water supply through a push button valve is formed, which acts against the action of a spring is movable into the open position.
  • This valve is So normally closed, so that in normal operation only a dry steam flow is emitted. Only for the case that a specially enhanced cleaning effect is necessary, the user can add reach liquid water by pressing the push button valve operated against the action of the spring, and this addition stops immediately as soon as the user releases the valve. This contributes in particular when saving water during operation and the operating time thereby lengthening. In practice there is a cleaning with dry steam completely sufficient in most cases, it is only for very extreme soiling useful, briefly the cleaning effect by adding of the liquid water to increase.
  • the steam cleaner includes a water reservoir 1, which is partially filled with water, so that a water space filled with liquid water 2 and a steam room located above the water level 3 4 result.
  • a heater in water room 2 5 which heats the water so far that in the steam room 4
  • Water vapor is generated under increased pressure for example can be the temperature inside the water reservoir can be increased to 130 C.
  • a steam line 6 leads from the steam chamber 4 to one Not shown in the drawing organ, for example to a spray tube or a mixing head, in the steam line 6, a closing valve 7 is switched on, preferably on the steam delivery member itself can be arranged.
  • a to riser pipe 8 immersed deep in the water space 2, which with a liquid supply line 9 connected, which in turn upstream of the Closing valve 7 opens into the steam line 6.
  • This Confluence is only shown schematically in the drawing, in fact, this is preferably done in such a way that the steam flow in the steam line perpendicular to one Liquid flow hits the liquid supply line.
  • a T-shaped Line piece are provided in the opening part with the steam chamber 4 in connection standing steam line 6 opens while the continuous Part of the liquid supply line on one side 9 is connected on the other side to the Steam delivery device leading steam line 6.
  • a metering or Closing valve 10 used, that in the illustrated embodiment is formed by a button valve which is to be actuated by a pushbutton 11. This is located on the outside of one of the water storage tanks 1 surrounding housing 12 of the steam cleaning device and is against the action of a spring, which is not shown in the drawing, can be pressed in. When pressed in, the dosing or closing valve 10 open, i.e. when you release the push button 11 this valve inevitably goes into the closed position about.
  • the metering or closing valve 10 can preferably be a continuously variable control valve, so that the Liquid release can be dosed into the steam jet can.
  • the User briefly by pressing the pushbutton 11 open the liquid supply line 9 and this leads that the high pressure of the steam in the steam room 4 hot water from the water room 2 through the Riser pipe 8 pressed into the liquid supply line 9 becomes. In this short-term liquid flow occurs the steam from the steam line 6 and thereby forms a homogeneous wet steam mixture, which then over the Closing valve 7 is supplied to the steam delivery element. It is possible by pressing pushbutton 11 to spray wet steam during the duration of the pressure and thereby the cleaning effect in the desired Way to increase.
